openfaces树表缺少js

Question

当尝试将RichFaces与OpenFaces合并到树表中时，它不显示任何展开折叠按钮。结果发现，有些js没有加载，这可能是造成这种情况的原因。

JSF代码如下：

<o:treeTable var="o">
                        <o:dynamicTreeStructure nodeChildren="#{bean.originNodeChildren}"
                                                nodeHasChildren="#{bean.originHasChildren()}"/>
                        <o:treeColumn expandedToggleImageUrl="/img/toggle-expand-light.png"
                                      collapsedToggleImageUrl="img/toggle-collapse-light.png">
                            <h:outputText value="#{o.description}"/>
                        </o:treeColumn>
                    </o:treeTable>

Bean代码被正确触发(包括hasChildren方法)。

JS异常：

使用OpenFaces版本2.0和RichFaces版本3.3.3。

Answer 1

需要在web.xml中为开放的faces配置资源筛选器，并完成这项工作。类似于：

public class OpenFacesResourceFilter extends ResourceFilter {
    // -- Fields --

    // -- Methods --
    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
        try{
            super.doFilter(servletRequest, servletResponse, filterChain);
        } catch (ServletException e) {
            Throwable parent = e.getCause();
            if(parent!=null && parent instanceof ServletException) {
                throw (ServletException) parent;
            } else {
                throw e;
            }
        }
    }
}

这看起来确实没有在应用程序的xml文件中声明OpenFaces资源筛选器。以下是关于如何声明过滤器的文档的摘录(请注意，您不必自己为该过滤器创建任何Java类)：

  <!-- FILTER FOR PROCESSING INTERNAL OPENFACES RESOURCES -->
  <filter>
    <filter-name>ResourceFilter</filter-name>
    <filter-class>org.openfaces.util.ResourceFilter</filter-class>
  </filter>

  <!-- MAPPING FOR OPENFACES RESOURCE FILTER -->
  <filter-mapping>
    <filter-name>ResourceFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

请参阅安装部分，以及OpenFaces 2.0文档中的OpenFaces部分。
